"shrubbery," early 14c., from Anglo-French bruce "brushwood," Old North French broche, Old French broce "bush, thicket, undergrowth" (12c., Modern French brosse), from Gallo-Romance *brocia, perhaps from *brucus "heather," or possibly from the same source as brush (n.1).

v.

late 15c., "to clean or rub (clothing) with a brush," also (mid-15c.) "to beat with a brush," from brush (n.1). Related: Brushed; brushing. To brush off someone or something, "rebuff, dismiss," is from 1941.

"move briskly" especially past or against something or someone, 1670s, from earlier sense (c.1400) "to hasten, rush," probably from brush (n.2), on the notion of a horse, etc., passing through dense undergrowth (cf. Old French brosser "travel (through woods)," and Middle English noun brush "charge, onslaught, encounter," mid-14c.), but brush (n.1) probably has contributed something to it as well. Related: Brushed; brushing.

brush

device composed of natural or synthetic fibres set into a handle that is used for cleaning, grooming, polishing, writing, or painting. Brushes were used by man as early as the Paleolithic Period (began about 2,500,000 years ago) to apply pigment, as shown by the cave paintings of Altamira in Spain and the Perigord in France. In historical times the early Egyptians used brushes to create their elaborate tomb paintings, while the ancient Chinese employed the tip of a long-haired brush to make the many intricate characters of their writing, a practice continued in the Orient today.
